The manifestations of climate change in precipitation, air temperature and simulated evapotranspiration for crops in the Tadla perimeter in central Morocco are examined. The study area is characterized by a semi-arid climate, with a potential agricultural vocation. This area is exposed to a scarcity of water resources for crop irrigation. To this effect, it is it is treating of rainfall in this area over 60 years (1958-2018) at 27 measuring stations and for temperature and reference evapo-transpiration (ETo) over 49 years (1969-2018) at 4 stations. Following data analysis by homogeneity tests on the agro-climatic time series (Pettitt test, Lee and Heghinian test, Buishand test and Hubert’s segmentation method). It is detecting that there are time breaks on annual rainfall, mean temperature and reference evapo-transpiration at the respective years of 1978, 1995 and 1978. Because of these breaks in time, rainfall is reducing by 36%, atmospheric warming is 1°C and the climate demand for evaporation coupled with plant transpiration increases by 13%. Consequently, the water requirement increases significantly in the agricultural area of crop production.
